The Allen Bradley 1762-RTC module, part of the MicroLogix 1200 series, is a dedicated Real-Time Clock that ensures accurate time and date functionality for programmable controllers. This module can be seamlessly inserted or removed from the MicroLogix 1200 controllers without causing damage, ensuring the system verifies its presence at startup to maintain precision in operations. The 1762-RTC's accuracy varies with temperature, with deviations ranging from as low as 25 seconds to over 200 seconds per month, and it features an internal battery designed to preserve settings, provided it is disabled during storage to minimize battery drain.
